Description As seen in the drawings, a conveyer constructed in accordance withthe presentinventionhas a frame which is partially supported and carried on wheels 15. The wheels 15 are mounted on an axle 16. The axle 16 is mounted'in bearings extended bracketwise from sliding sleeves 17. The

sleeves 17 are slidably. mounted on a vertical U-shaped supporting frame comprising the standards 18, connected by across bar 18 at their base, and secured by pins extending through the perforations'19. The perforations 19 are arranged 'to permit a vertical adjustment of the standards 18-and the conveyer frame supported thereby.

The belt conveyer frame is mounted on a supporting bracket comprising a pairof vertical standards 18,18 secured to the belt conveyer frame 'at a point adjacent its longitudinal center and'between its center of gravity and its discharge end, a cross bar 18 provided between the standards 18 and below the conveyer frame and a pair of struts .or bars 21 extending from the lower ends of the standards 18 to the conveyer frame at a point adjacent its receiving end. I prefer to secure the standards 18 and the struts 21 to the conveyer frame by ineans' of counterpart socket members 20 and '20 respectively mounted on pins or cross bars 20, 20 respectively in the frame.

The ends 22 of the bars 21 are tubular to act as sockets for-lifting handles 23. The handles 23 are detachably secured to the ends 22 and are employed to permit an at tendant or operator to lift the receiving end of the conveyer.

The conveyer frame normally rests on its receiving end and is supported in an inclined position on the wheels 15, the standards 18 being secured to the frame at a point between its'center of gravity and'its discharge end.

The wheels 15 are so placed that when the lower end of the conveyer frame is raised,

the center of gravity of the conveyer frame is disposed substantially in line with the axle 16, or, in other Words, the total weight of the conveyer is poised on the carrying wheels 15.

WVhen the conveyer is actively disposed, the handles 23' are withdrawn from engagement with the socketed ends 22.

The frame or. housing of the'conveyer, as best shown in Figs.,1 and 3 .of' the drawings, is constructed of angle bars 24 and 25. These bars extend the full length of the frame and are'held in parallel spaced relation by braces 26 andcheek plates '27. The

' plates 27 operate to prcventcoal or other ma terial being handled by the conveyer from passing to the inner side thereof to be deposited on the under or inner side of the conveyer belt 28. The conveyer belt 28 extends lengthwise of the frame formed by the angle irons 24 and 25, and is supported mainly by "thedrunis 29 and 30. The drum 30 is an idler and is located between ashoe plate 31 and a flexible apron32. Thedruni 29, as shown best in Fig. 2, has bearings in sliding blocks 33. To adjust the blocks 33 is the function of the feed screws 34, which engage the-blocks 33 tomove' the same lengthwise of and in guided relation to the angle bars 24 and25.

'over the lower end of the belt 28, bridges the i a space between the nosing and the belt and acported by rollers 35. The rollers 35 have pintle journals'for which are provided bearings in the supporting rails 36. The. outer edges of the'belt 28: overhang andrestuponj the rails 36, which maintainthe edges of-said belt in fixed and close approximation to'the lower edge of the cheek boards 37 and prevent'sagging of the edges of the belt between the'rollers 35. The belt 28. is suitably provided at intervals with cleats 38. The cleats 38 are preferablyconstructed of rubber, As

seen best in Fig. 3 of the drawings, the. cleats 38 extend above the belt 28 andbetween the cheek boards 37. The cleats serve in the active practice of the conveyer, t-o'maintainthe.

ference by the material being handled, withthe underside of the belt where the same turns around the drum 30.

The nosing 44 is rigidand isjfixedly. connected with the apron 32. The apron 32 rests commodates the action of the said belt and of the cleats 38 mounted thereon. Through the agency of the apron 32 and the vibration imparted thereto by said cleats the coal or f other material being handled is agitated and spread prior to being delivered to the belt 28,

to be conveyed to the delivery end thereof.

The agitation. referred to as being imparted through the agency of the apron 32, is augmented by a tappet cam or eccentric 45 mounted at the end of the shaft bearing the drum 30, and extending beyond the plates 27. The cam'45', as seen best in Fig. 5 of the drawings, is employed in conjunction with a pintle bar 46. Thepintle bar 46 in the present construction is usually formed from one of the handle bars'23. It is furnished with a pointed end for driving into the ground or floor over which the conveyer is working.

The operator having set the pointed end of the bar 46, moves the bar into the path of the eccentric 45, so that the same engages the said baras the drum 30 rotates. It is obvious that "the result ofsuchaction is to break up any solid formation of the pile being con-.

veyed, and to force the nosing 44 intothe pile until the upper stratum thereof rolls upon the apron 32 and belt 28. As best seen'in'Figs. 3 and'4 of the draw' ings, the central section of the belt 28 is sup- In Fig.7 of the drawings, a modified form of the' eccentric is shown, the modification embodying a disk 47, which has an arcuate slot 48. V Pivotally mounted on the disk 47, is a bearing plate 49. A perforated boss extends from the vplate49. The axis of the perforation in the boss 50 coordinates with the center of the slot 48, when the plate 49 swings on the pivot 51 with which it is provided. The boss 50 tightly fits the end of the pintle of the drum 30 to be rotated therewith. The plate 49 is perforated at the end opposite. the pivot 51v to receive a coupling pih 52. The pin 52 also engages any one of the sockets 53 with which the disk 47 is provided. The sockets 53 are arranged in a line concentric Withthe' pivot 51 and median line of the slot 48. It is evident that as the pin 52 is disposedin one'or other of the perforations 53, the eccentric arrangement of the disk 47 is modified relatively to the center of the drum 30.. In this manner, provision is made for increasing or diminishing the vibratory action of the' disk 47 onthe bar 46.

In Fig. 8 of the drawings, a modified arrangement of the eccentric is disclosed. In this arrangement, an ovate cam 54 iskeyed to the drum 30.. The long diameter of the cam 54 is greater than the distance between the axis of the drum 30 and the bottom of the shoe plate 31. As a result of this construction, the cam 54 strikes upon the floor or ground on whichthe plate 31 is resting and lifts'the same and the'coal or other material superimposed thereon.

It will be understood that the employment vented thereby from rolling backward tothe receiving end of the conveyer.

As set forth hereinbefore, the plates 27 and the shoe plate 31 constitute a conveyer booth. Part of the function of the apron 32 is to permit any material which might find lodgment in the booth and on the apron 32thereof to escape to be dislodged or forced upward by thecleats 38. It is obvious that the apron 32 will uplift and relieve any pressure from below imparted in the manner indicated.

While the cheek boards 37 and supporting rails 36 operate efliciently to prevent any lodgment of particles or the accumulation of grit and dust on the inner side of the belt- 28 and on the lower reach thereof, in such op-' erations as those in which the conveyer is employed, it is impossible to entirelyexcludethe particles of grit and dust. If such mate- 'rial reaches the drum 30, it is obvious that it will adhere to the surface thereof and accumulate to the ultimate efiect that the diameter of the drum and coating thereon is increased and the perfectworking adjustment of the apparatus might be destroyed. To avoidthis, a scraper plate 58 is provided.

As seen best in Fig. 4 of the drawings, the plate 58 has a scraping end disposed'in close approximation to the drum 30. The scraping end of the plate 58. is supported by an angle iron 59. The lower end of the angle iron 59, in service rests close to the upper surface of the lower stretch of the belt 28. This serves to remove any adhesions on the inner surface of the belt 28,'which have escaped the scraping e ge of the bolster 60, which, as

shown, supports the tail end of the plate 58.

The bolster 60 also supports inclined shelves 61', which are disposed in receiving relat1on to the plate 58. The outer end of the shelves 61 extends through openings 62 shown in Fig. 1 of the drawings. If any material passes thescraping edges f the bolster 60 and the angle iron 59 and nnds lodgment on the drum 30, the scraping end of the plate 58 serves to dislodge the same. The material thus removed from the drum 30, is drawn by the belt 28 over the plate 58 and delivered to the shelves 61, and in turn is delivered by the said shelvesbevond the plates 27 and outside of the apparatus.

Operation hen operating with a conveyor constructed and arranged as above described,

and as shown in the accompanying drawings,

an attendant desiring to move the conveyer, places the handles 23 inthe sockets provided in the ends 22 of the 133F321. -The lower. end of the conveyer i's' then lifted from the ground, when it will be found that the weight of the conveyer is nicely balanced on the carrying wheels 15. p The conveyeris then moved to any location and the nosing 44 is disposed at the lower edge of a pile or drum of material to be conveyed. The handles 23are then re moved and the attendant presses the nosing 4A of the conveyer into the pile, using the bar 46 for this purpose. If a wagon o'r'other vehicle is to be loaded from the drum, the wagon or vehicle is brought under the delivery end of g the conveyer. The motor 40 is then started. The attendant using'the pinch bar46 or one of the handles 23, as indicated, presses against the cam 45, forcing the nosing 44 well under the dump or pile, where the surface material will flow to the apron 32 and belt 28 incident to the vibrating'operation of the eccentric'45, as above described.

. The material of the dump flowing" as it does to the conveyer, "is carried the'rebyover the head or delivery end of the conveyer, and deposited in the Wagon or vehicle. -When the vehicle has received its complementflor load, the motor 40 is discontinued and the co n veyer brought to rest to await'the disposition of a second vehicle at the rceivingstation.

If the vehicle is low or'fo'r'any reason it is Vdetermined'to change the inclination of "the conveyer and supporting frame therefor,

this is accomplished by withdrawing the'pins' from the perforations 19 in'which they'rest for supporting the standards 18. The standards are then moved tothe desired elevation and the supporting pinsreinsertedl raw-111 be noted that in this adjustmenh the operative relation of the belt' ll is not disturbed.
